A structure of the electron is presented, based on the model proposed by the author. Assuming the electronic charge to be a scalar field, and using the variational principle, a new action function in Weyl geometry leads to a set of field equations. These equations are identified as the Einstein‐Maxwell‐Schrödinger equations. It is proposed that the covariant modified Schrödinger equation describes electron dynamics at the subatomic level. The ψ function of quantum mechanics is replaced by an in‐invariant field in Weyl geometry. Tentative ideas to test the massless electron motion in ballistic devices and superconductors are also discussed.
